3 Day View option

I would like to have a 3-day view option. I have a computer shop where people regularly request appointments for the next day or two days. I am also a freelance insurance agent. At this work, I must schedule appointments as soon as possible, otherwise I lose the sale.  

Having a weekly view calendar is convenient. However, in my busy schedule it is more efficient for me to have a three-day view calendar to maximize appointment efficiency. Another reason that I prefer a three-day view instead of the week view is that I already created some appointments where I later reviewed them to be not the optimal option. That is because my OneCalendar has too many items on it, and I began to create appointments that are not optimized. 

A 3-day view would help me so much to keep creating the most efficient appointments and it would reduce the stress of creating appointments in a weekly view.
